The return air is dried and heated through the drying cartridge.
(2) Condition process While the sterilant is injected into the air flow, dry air continues to circulate until just before the sterilant gas leaves the device. The conditioning step is a step to quickly reach the target sterilization concentration.
(3) Decontamination step Maintain the entire concentration of sterilizing gas in the isolator with a sterilizing agent for a specified time, and sterilize the work room and gloves for work.
(4) Aeration Step Stop the injection of sterilant and circulate dry air for a certain period of time to lower the concentration of sterilizing gas in the isolator and connecting hose.

  The work gloves are made of thin rubber, and when the worker pulls out the arms from the gloves, the work gloves hang down to contact the surface of the work equipment in the work room or the wall of the work room, the surface of the glove or each The fingers may overlap and contact, resulting in poor sterilization of the contacted portion.

  Hereinafter, an embodiment of the present invention for solving this problem will be described with reference to the drawings. In the drawings for describing the embodiments, the same components are denoted by the same names and symbols as much as possible, and the repetitive description thereof will be omitted.

  FIG. 5 is a perspective view showing the glove sterilization support member of the first embodiment. 6A shows a front view of the glove sterilization support member of Example 1, and FIG. 6B shows a side view of the glove sterilization support member.

  The glove sterilization supporting member 100 according to the first embodiment includes the support 110 extending from the arm of the glove to the tip when inserted into the glove, and the support 110 is bent at the bending portion 115 in the middle. The rear support 110a on the arm side and the front support 110b on the hand side. A rod-like reinforcing portion 120 is attached to the rear support 110a and the front support 110b to connect them.

  In the vicinity of the bent portion 115 of the support portion, a ring-shaped expanded glove arm portion 130 is attached, which expands the arm portion of the glove when inserted into the glove. The glove arm enlargement 130 may be fixed by welding, brazing or the like to the support 110 at a part of the ring. The glove arm enlarged portion 130 may be attached to the reinforcing portion 120.

  A ring-shaped enlarged palm portion 140 is attached to the tip of the front support 110a, which spreads the root of the forefinger of the glove when it is inserted into the glove. The globe palm enlarged portion 140 may be attached by welding, brazing or the like to the support 110 at a part of the ring.

  The foremost end of the front support 110 b is adapted to fit and connect a vinyl tube 150. The vinyl tube 150 is inserted into the forefinger of the glove, and may have a length that can reach the tip of the forefinger.

  It is desirable that the length of the tip of the vinyl tube 150 be in contact with the fingers of the glove. This makes it possible to eliminate or reduce wrinkles on the glove fingers.

  By having the palm enlarged portion 140, the glove sterilization support member 100 can be easily inserted into the glove palm. In addition, by providing the vinyl tube 150 at the tip of the palm enlarged portion 140, the insertion to the finger part of the glove becomes easy.

  Furthermore, the vinyl tube 150 may be any member, but by using a member softer than the glove, even if the vinyl tube contacts the finger portion of the glove, the scratch is difficult to occur. Since a scratch is hard to occur, the number of steps when the user inserts the vinyl tube 150 can be reduced.

  If the length of the vinyl tube 150 is longer than the length of the glove fingers, the length of the vinyl tube 150 is adjusted precisely because the vinyl tube 150 member is softer than the glove and is bent in the glove fingers. There is no need for this, and the convenience of the user's sterilization operation can be improved.

  At the rear end side of the rear support 110a, a substantially ring-shaped attachment portion 160 lacking a part of the circumference is provided for attaching the glove sterilization support member to the glove port. The mounting portion 160 is provided with a plurality of stopper portions 170 at a plurality of circumferential positions.

  The glove sterilization support member of this embodiment can be manufactured by bending a wire made of metal, for example, stainless steel, and fixing necessary portions by welding, brazing or the like.

  The glove for work is made of thin rubber, for example, chloroprene rubber with a thickness of 0.4 mm, and when the worker pulls out the arm from the glove, it hangs down in the work room and contacts the surface of the work equipment or the work room Also, the surface of the glove comes in contact with the glove by the heel. The thickness of the glove is preferably about 1.0 mm or less in consideration of workability. However, it can be implemented even if it is 1.0 mm or more.

  Even if the sterilizing gas is supplied in this state, the sterilizing gas may not spread over the surface of the working chamber or the entire surface of the glove and sufficient sterilization may not be performed. In addition, since the amount of contact with the sterilizing gas is smaller at the portion where the surfaces of the gloves contact each other or the portion where the glove is in contact with the isolator chamber, the sterilization time needs to be longer.

  Therefore, at the time of sterilization, the support member for glove sterilization of the present embodiment is inserted into the working glove, and the working glove is supported in the working chamber, so that the contact portion can be reduced and the sterilization can be performed efficiently. .

  The ring-shaped mounting portion 160 cut off a part of the circumference is contracted and inserted into the glove port provided on the front door, and the mounting portion 160 is expanded by a spring force to fix the glove sterilization supporting member to the glove port Do. Since the mounting portion 160 is provided with a plurality of stopper portions 170, the insertion position of the glove sterilization supporting member is defined, and the glove is not broken by excessive insertion.

  A bending portion 115 is provided in the middle of the support 110 of the glove sterilization support member, and a reinforcement 120 is attached to connect the front support 110b and the rear support 110a. Further, in the vicinity of the bent portion 115, a ring-shaped glove arm enlarged portion 130 is provided.

  That is, the glove arm enlarged portion 130 is provided closer to the bending portion 115 than the central portion of the rear support 110 a. Although the glove arm enlarged portion 130 can be provided closer to the bending portion 115 than the central portion of the front support 110b, it is substantially parallel to the attachment 160 when provided on the rear support 110a. Therefore, it becomes easy to support the glove. In addition, insertion into the glove is facilitated.

  Since the arm portion of the glove is supported by the reinforcing portion 120 and the ring-shaped glove arm enlarged portion 130, it is possible to suppress and support the occurrence of wrinkles in the glove near the bent portion. In addition, although the weight of the glove is supported by the support portion 110, the supporting strength can be increased by the reinforcing portion 120.

  Furthermore, if the depth of the working chamber is short compared to the length of the glove, when the glove is supported horizontally, the tip of the glove may come in contact with the back of the working chamber. In the glove sterilization supporting member of this embodiment, since the support column 110 is bent at the bending portion 115, the tip of the glove can be supported in the working chamber without contacting the back surface of the working chamber.

  A ring-shaped enlarged glove palm portion 140 is attached to the tip of the front support 110a, which spreads the root of the forefinger of the glove when inserted into the glove. Further, the forefront of the front support 110 b can be connected by fitting the vinyl tube 150, and the vinyl tube 150 to be inserted into the forefinger of the glove can be attached.

  By adjusting the length of the vinyl tube 150 in accordance with the length of the glove finger, it is possible to maintain a low wrinkle state. Further, by inserting the vinyl tube 150 into the forefinger and widening the root of the forefinger by the ring-shaped palm enlarged portion 140, the tip of the glove is expanded as a whole, and the occurrence of wrinkles and the overlapping of the surface are suppressed.

  The finger of the glove has a large angle between the thumb and the index finger, but the angle between the index finger, the middle finger, the ring finger and the little finger is smaller. By supporting the forefinger with the vinyl tube 150 or the like, contact of each finger of the glove can be prevented.

  The ring-shaped glove arm enlargement 130, the ring-shaped glove palm enlargement 140, and the substantially ring-shaped attachment 160 are each attached to the support by welding, brazing, or the like at a part of the ring circumference. Structure is simple.

  Then, when the support member for glove sterilization is inserted into the glove, the support column 110 and the reinforcing part 120 contact the glove over the entire length to support the glove, thereby suppressing the generation of wrinkles due to the sag of the glove. Can. Even when wrinkles are generated, the gloves are placed on the support portion 110 and the reinforcing portion 120. Therefore, overlapping of the wrinkles is suppressed, and efficient sterilization work can be realized.

  FIG. 7 shows a state in which the glove sterilization support member of this example is inserted into a working glove. As can be seen in the figure, there is no contact between the surfaces of the glove at the arms of the glove and no contact between the fingers at the tip.

  According to the glove sterilization supporting member of the present embodiment, the working glove can be supported in the working chamber in the expanded state with a simple structure, and the working chamber of the working glove or the isolator can be effectively sterilized. Can.

  As shown in FIG. 4, at the time of sterilization, the pass box side opening / closing door 26 of the working chamber 12 is opened so that the sterilizing gas flows to the pass box 40 through the connecting portion 48. Since the glove attachment opening on the pass box side (right side) shown in FIG. 1 is provided near the pass box side opening / closing door 26, when the pass box side opening / closing door 26 is opened as shown in FIG. The tip of the glove may come in contact with the pass box side opening / closing door 26.

  The present embodiment solves this problem, and FIG. 8 shows a plan view around the pass box side opening / closing door 26. As shown in FIG. Although the glove sterilization support member 100 is usually attached so that the front side support portion 110b rises upward, in the present embodiment, the glove box sterilization support member 100 on the pass box side is rotated 90 degrees to the right, The front side support portion 110 b is attached so as to enter the connection portion 48 with the pass box and the pass box 40.

  Therefore, the tip of the glove faces the back of the pass box 40 or the back of the connecting portion 48 with the pass box. In this embodiment, a slit for suctioning sterilizing gas is provided on the back of the pass box and the back of the connecting portion on the extension of the tip of the glove.

  In FIG. 8, reference numeral 47 denotes a slit provided on the back of the pass box, and reference numeral 49 a denotes a slit provided on the back of the connecting portion 48. The slit for sucking the sterilizing gas may be provided on the bottom surface of the connecting portion 48 as indicated by reference numeral 49b.

  By providing a slit for sterilizing gas suction on the extended line of the glove tip or on the bottom of the glove tip, the tip of the glove can be effectively stretched by the air flow for effective sterilization, and re-scattering of contaminants attached to the glove. It can be suppressed.

  According to this embodiment, the working glove disposed on the pass box side can also be favorably sterilized.

  In the third embodiment, the glove sterilization support member of the present invention is provided with a drive unit for moving the tip end of the support.

  FIG. 9 (a) is a front view of the glove sterilization support member of the present embodiment, and FIG. 9 (b) is a side view of the glove sterilization support member of the present embodiment. As shown in the figure, a drive unit 180 is provided in a part of the support column 110, and can be operated by the operation unit 190.

  By moving the front side support column portion up and down or left and right periodically by the drive device at the time of sterilization, it is possible to move the working glove into which the glove sterilization support member is inserted up and down or left and right. Thus, the sterilizing gas in the working chamber can be agitated to suppress stagnation of the air flow.

  Further, at the time of sterilization, the front support portion is moved by the drive device to move the position of the glove. As a result, since the air flow flows along the moved glove, the air flow of the sterilizing gas can be controlled, and the sterilizing time can be shortened. For example, although the air flow may stagnate at the corners of the working chamber, it can be effectively sterilized by changing the flow of the air flow using the glove sterilization supporting member of this embodiment.
